							(a)
The correct option is (B) v = c.
A pilot on a space ship moving at 0.86c away from the Earth sends a laser beam signal to Earth. Light wave is an electromagnetic wave. Its value will be same irrespective of the frame reference. Therefore the pilot measures the speed v of the laser beam signal to be equal to the speed of light c. From the above observation we conclude that, option (B) is correct.
